New rear wheel last night with both tires pumped up, off for my daily
ride this evening.
About five miles out, a goathead flashes by on front tire, left side.
Brush it off, hope that the Slime sealant holds. At least it's not
spraying green gunk.
By the top of the ridge west of town, denial is useless. Stop, squeeze
soft front tire, shake head, begin repair. At least the rear tire is
okay.
Pry out nine goathead thorn tips from tire with paper clip carried for
that purpose. Several ooze green slime, but none hiss.
Pump up replacement Slime tube lightly to test it. Worthwhile
precaution, since there's a sudden hiss. Is that the pump head coming
off? No, it's a small seam split.
Pump up second replacement Slime tube. Admire how it holds its breath.
Pop it in the tire, pop the tire on the rim, pump it up. Very pleased
with Topeak Road Morph--little foot stand, t-handle, in-line air gauge,
goes to 120 psi almost easily compared to older, smaller Zefal
no-foot-stand, no t-handle pump. I like the pump-head lever better,
too.
Foolishly pick up and pack things, chasing valve caps rolling away in
wind.
Give rear tire a squeeze. While I was repairing the front, the rear was
quietly going soft. Curse, get paper clip out, squint at rear tire.
Remove three goathead thorn tips. One has a drop of dark green fluid,
but no bubble or hissing.
Attach pump, reads 30 psi, leak apparently plugged with Slime. Two more
spare tubes, both just ordinary tubes with long valves in case I meet
gorgeous women with flat tires and deep aero rims. Five Park glueless
patches, which worked nicely the only time that I used one.
No hissing. The ride home from the top of the ridge is usually 18
minutes or less. To hell with it, pump rear to 120 psi, no hissing,
ride home. Rear tire is still holding pressure when I reach my
driveway.
Walk dog. Dog stops, lifts front paw, looks at me expectantly. Remove
goathead from paw.
Later, go out to garage to replace tube. Good idea. Rear tire that held
for over six miles is now completely flat.
Dunk front tube in sink, inflate. That's the tube whose tire still had
nine thorn tips. Four punctures bubble merrily.
Dunk rear tube in sink, inflate. Only three thorn tips were dug out of
its tire, and it held air all the way home after I pumped it up. Three
punctures belch green Slime into the water.
It looks as if Sunday's heavy rain and hail washed a few extra
goatheads onto the path and road.
